Abstract

A battery separator paper suitable for use in an alkaline battery comprises a web of polyolefinic synthetic pulp fibres and fibres effective to reinforce the polyolefinic fibres. The polyolefinic synthetic pulp fibres are not substantially heat-bonded to each other or to the reinforcing fibres but are bonded to each other and the reinforcing fibres by means of an alkali-resistant hydrophilic binder, e.g. polyvinyl alcohol. The reinforcing fibres may for example be polyvinyl alcohol, rayon, PVC or nylon. The battery separator paper is made by conventional papermaking techniques.
